25 - APPENDIX B - RECORD OF TEST RESULTS

Specifies conditions for carrying out the tests and includes nominal dimensions and tolerances for standard and subsidiary test pieces and requirements for the testing machine, its installation and initial calibration. Guidance on the maintenance of the machine and a method for determining friction losses are included in an appendix.

This standard specifies the conditions for performing the Izod impact test on metals with particular reference to ferrous metals. It also includes requirements for the installation of the testing machine, its initial and periodical calibration, and its maintenance by the user.The test consists in measuring the energy absorbed in breaking, by one blow from a pendulum, a clamped notched test piece. The test piece is clamped vertically in supports with the notch in the same plane as the upper face of the support. The blow is struck on the face containing the notch and at a fixed distance above it.NOTE: The test piece may have a square, a rectangular or a circular section. Where a requirement involves reference to a face of a test piece, it applies directly to square or rectangular test pieces and by implication, to the corresponding portion of the surface of a circular test piece.
